► High Voltage Ultra Precision
Precision High Voltage Op
Amps were Developed on
Intersil’s New PR40 Process
Precision high voltage op amps were developed on
Intersil’s new PR40 process. PR40 is a new precision
process that enables Intersil to develop competitive
precision high voltage amplifiers. Key features of the
new process are full DI, complementary bipolar, low
noise, well-matched Super-beta transistors, P-channel
JFET, high breakdown voltage (>44V), high density
capacitors, Thin Film resistors, fuse-link trim cells, and
high ESD cells. (Figure 1)
Features and benefits
• Full dielectric isolation (DI) and high ESD cells (>4kV ESD
HBM) provide highly robust inputs compared to older
process amplifiers.
• Thin film resistors and fuse-link trim cells offer very low
offset voltages (Figure 2)
